SUNLU PLA 3D Printer Filament Magenta 1KG

Print settings and mechanical properties

The manufacturer publishes a full parameter set for this line: 1.75 mm diameter with a stated +/- 0.02 mm tolerance, density 1.23 g/cm3, tensile strength 40 +/- 6 MPa, flexural strength 65 +/- 6 MPa, elongation 10 +/- 5 %, notched Izod impact 5 +/- 3 kJ/m2, melt flow index 6.9 +/- 3 g/10 min, heat deflection 55 +/- 5 C and Vicat softening 54 C. Print settings are 200-210 C nozzle at 50-100 mm/s or 210-240 C at 100-200 mm/s, with a 50-60 C bed and retraction of 0.8-1.2 mm at 30-40 mm/s. Shrinkage is 0.1-0.3 % and Shore hardness is 80. The manufacturer also claims neat winding to reduce tangling and compatibility with 99% of FDM printers; the latter is an unmeasured marketing claim. No instrumented laboratory test from a major test outlet was found, so the published values are the only quantitative property data available.

Print quality in practice

Hands-on evidence is thin. A comparison site rates standard PLA below PLA+, PLA+ 2.0 and PLA Meta in strength, impact resistance and heat resistance, noting all soften near 54 C and are unsuitable for hot environments. No Reddit or forum threads on this exact filament were located in the searches used, and color-specific behavior for Magenta was not separately tested in any source.

Heat, moisture and storage

Heat resistance is limited: all SUNLU PLA-based variants soften around 54 C, consistent with the manufacturer’s Vicat softening temperature of 54 C and heat deflection temperature of 55 +/- 5 C. It is not suitable for hot environments such as car interiors. The manufacturer page does not give storage instructions.

Is it worth it?

SUNLU’s store listed standard PLA from $10.29/kg on sale (regular $18.99/kg) at the time of check, and 6 kg bundles are available. A 2023 review reported standard PLA at $12.99/kg and PLA+ at $13.99/kg. Ownership costs are the filament itself, optional desiccant or a dryer, and electricity for drying; there is no subscription or capsule lock-in. Value thresholds from the sources: at or below about $11/kg it is strong value for beginners and for prototypes or display parts; $12-16/kg is fair value, with a comparison against PLA+ if strength or bed adhesion matters; $17-20/kg is weak to fair, where the store’s regular price sits; above $20/kg it is weak value for standard PLA, and buyers should step up to PLA+, PLA+ 2.0 or PLA Meta. The main value differentiator is cost plus consistency and color range, not strength or heat resistance, which are limited. Filament is a consumable with no warranty; returns are allowed within 7 calendar days and exchanges within 15 calendar days under SUNLU’s stated conditions, and opened or used consumables are not returnable except for confirmed quality issues.

Which model this is

This page covers SUNLU standard PLA, not PLA+, PLA+ 2.0, PLA Meta or any specialty PLA line. The researched variant is Magenta, 1.75 mm diameter, 1 kg spool. Magenta is one of 20 listed colors with hex code #C52E79; diameter options on the same page are 1.75 mm, 2.85 mm and 3 mm, and weight options are 0.25, 0.5, 1, 2, 3 and 5 kg. No separate model number, SKU or revision code is published on the manufacturer page, and no color-specific or revision differences for Magenta were documented. The Amazon listing for this product is ASIN B0XXXXXXXX.
